These regulators feature extremely TPS7225 TPS7230 low dropout voltages and quiescent currents pared to conventional LDO regulators. TPS7233 Offered in small-outline integrated-circuit (SOIC) packages and 8-terminal thin shrink small-outline TPS7248 (TSSOP), the TPS72xx series devices are ideal for cost-sensitive designs and for designs where board space is at a premium. TPS7250 A bination of new circuit design and process innovation has enabled the usual pnp pass transistor to be replaced by a PMOS device. Because the PMOS pass element behaves as a 0 0 50 100 150 200 250 IO - Output Current - m A low-value resistor, the dropout voltage is very low - maximum of 85 m V at 100 m A of load current (TPS7250) - and is directly proportional to the Figure 1. Typical Dropout Voltage Versus Output Current load current (see Figure 1). Since the PMOS pass element is a voltage-driven device, the quiescent current is very low (300 µA maximum) and is stable over the entire range of output load current (0 m A to 250 m A). Intended for use in portable systems such as laptops and cellular phones, the low-dropout voltage and micropower operation result in a significant increase in system battery operating life. The TPS72xx also Features a logic-enabled sleep mode to shut down the regulator, reducing quiescent current to 0.5 µA maximum at TJ = 25°C. Other Features include a power-good function that reports low output voltage and may be used to implement a power-on reset or a low-battery indicator. The TPS72xx is offered in 2.5-V,...
